Chromium doesn't need gecko-mediaplayer. In fact, I'm able to view the Phoronix site on Chromium 31 without gecko-mediaplayer. In addition, Chromium isn't a Gecko browser; it's a Webkit browser. Firefox and Wine's version of Internet Explorer are based on Gecko.
I would try going to about:plugins and disabling everything that mentions gecko.
